Wireless Terminology
- Single band supports only the 2.4GHz band
- Lots of wireless devices (phones, computers, appliances, etc) use this band – therefore, it’s very “congested” or “noisy” and can inhibit performance
- Dual band supports both the 2.4GHz and 5GHz band
- 5GHz band is much less congested, therefore providing a better wireless experience especially for things like wireless display (WiDi / Miracast)
- There are more & wider channels in the 5GHz band compared to 2.4GHz
- 1x1 = 1 send antenna and 1 receive antenna (150Mbps throughput for 802.11n / 433Mbps for 802.11ac)
- 2x2 = 2 send antennas and 2 receive antennas (300Mbps throughput for 802.11n / 866Mbps for 802.11ac)
Antenna Configuration | 802.11n | 802.11ac |
Single stream (1x1) | 150Mbps | 433Mbps |
Dual Stream (2x2) | 300Mbps | 866Mbps |
